I've just come up with a first attempt at this, that seems to work:

| header   __TO_NOREALNAME        To =~ /^["\s]*\<?\S+\@\S+\>?\s*$/
| header   __TO_GOODREALNAME_JOHN To =~ /^\"?john\s+wilcock\"?\s+\<?john\@\S+\>?\s*$/i
| header   __TO_JOHN              To =~ /john\@/i
| meta     local_BADREALNAME_JOHN __TO_JOHN && !__TO_GOODREALNAME_JOHN && !__TO_NOREALNAME
| describe local_BADREALNAME_JOHN To John but with wrong real name
| score    local_BADREALNAME_JOHN 2.0

but only for me personally, of course. Anyone any comments on whether
this rule could be improved or optimised? I'm sure it ought to be
possible to write a single regex rather than these three meta-rules...

And how about the more general case I mentioned:

Any takers?

John.
